BUTTON.

SPECIFICATION forming part of Letters Patent No. 333.794, dated January 5, 1886.

Application filed April 7, 1885. Serial No. 161,436. (No model.)

To all whom it may concern: I Be it known that I, GEORGE W. ToMs, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In said drawings, Figure lis a plan ofabutton. Fig. 2 is a section through x of Fig. 1. Fig. 3 is a sectional view similar to Fig. 2, showing the arrangement of a peculiar form of bar. Fig. 4 is a sectional view of a button like that illustrated in Figs. 1 and 2, provided with an oval or rounded face. Fig. 5 is a section taken through y, Fig. 1, and Figs. 6, 7, 8, and 9 are detail views of various forms of bars.

rlhe invention illustrated in the above-described drawings relates to improvements in those buttons having a face and back plate united at their peripheral edges, central perforations in both of said plates, and a bar diametrically arranged across said perforations, the improvement consisting in forming the faceplate with a central perforation havinga deep depending flange around the same, and the back plate with a deep cup-shaped portion or hub in which the cross-bar is placed, eX- tending from side to side thereof, said hub having a central perforation therein, with the bar held loosely between the lower edge of the ange on the face-plate and the bottom of the hub, and adapted to rotate therein.

The object of the invention is to provide a metallic button with a thin edge, to allow of its ready insertion in the button-holes, and a deep hub, whereby the button is set off or held away from the goods, and, further, and more particularly, to arrange the cross-bar loosely in the bottom of the hub, terminating at the sides thereof, whereby the thread is sunk below the surface of the face-plate and protected from abrasion, and also to lower the said bar near to the goods, so that there is but a short length of thread between the goods and the bar.

In the figures of the drawings, a is the faceplate, and b the back plate, which are united at the edges thereof by lapping the face-plate over the back plate, as indicated in Figs. 2, 3, Sto. The back plate is formed with a deep hub, b', having a central perforation or threadopening therein, the remaining portion of the plate being continued straight out, or approximately so, until it joins the face plate. In the face-plate a, is a central perforation with a deep liange, a', around the same extending downward within the hub b in the back plate, leaving an annular space between the lower edge of the liange and the bottom of the hub. On the bottom ofthe hub is arranged a crossbar, c, diametrically across the thread-opening, which terminates at the sides of the hub and does not extend out to the periphery of the button between the plates, thereby causing the thickening of the edge of the button, which is undesirable. The bar is held down in the bottom of the hub and prevented from slipping up between the plates by the iiange a', rotating freely between the lower edge of the ange and the bottom of the hub in the annular space therebetween, whereby the strain upon the thread is greatly lessened.

In Fig. 3 the bar is bent at the ends and projects slightly over the edge of the hub between the plates. This form gives a stronger bearing-surface for the bar as it rotates; but the bar stopping at the sides ofthe hub is preferred.

Instead of a simple straight bar, as indicated in Figs. 1, 2, 4,and 5, I may use the forms shown in Figs. 6 and 7 or any analogous forms; but the bar, whether straight or curved ,is arranged on the bottom of the hub and extends from side to side thereof.

I am aware that metallic buttons having perforated face and back plates with a slight depression in the back plate are old; also, that notched flanges have been formed on said face and back plates, and a cross-bar placed insaid notches; but in all these buttons the bar is held away from the goods midway between the plates and extends in between the said plates, thickening the edge of the button. It is further known thata loose bar is not in itself entirely novel, but said bars have extended from one side of the button to the other.

In my improved button the bar rests loosely in the bottom of a deep hub in theback plate and does not extend to the periphery of the button, but terminates at the sides of the hub, being confined Within the hub by the flange on the face-plate, which, as above described, pro- 5 jects downward into the hub, leaving an annular space between the lower edge Yof the same and the bottom of the hub in which the bar can rotate.

Having described my invention, I desire to Io claim the following:

The herein-described button, consisting of the front and back, a b, provided with flanges a b, and aI cross-bar placed in the hub or de- Witnesses:
